mmap_read \- memory map a file for reading
.B #include <mmap.h>
char* \fBmmap_read\fP(const char* \fIfilename\fR,size_t* \fIfilesize\fR);
mmap_read opens \fIfilename\fR for reading, maps the whole file into
memory, closes the file, writes the length of the file to \fIfilesize\fR
and returns a pointer to the mapped file.
The file is unmapped by the operating system if the process terminates.
It can also be manually unmapped by calling \fBmunmap\fR from
If the file could not be opened or mapped, (void*)0 is returned.
